The Speedy Bee F405 50A Stack V3 includes all the features a user would expect from a modern flight controller and ESC stack, but at an incredible price. The F405 V3 flight controller features the STM32F405 MCU, an onboard 4-level battery life indicator, a Micro-SD card slot for Blackbox logging, 4 groups of LED strip pads, a DJI plug for digital quads, and built-in Bluetooth for wireless configuration through the SpeedyBee App. The 50A 4-In-1 ESC features a built-in TVS protective diode, and Japanese made TDK SMT capacitors, and even comes with a low ESR 1500uF capacitor.
